First boot load bios factory defaults, save and exit and then at the next boot disable security options
You must fill your DMI manually.

Hello guys,

Need help to recover bios. Laptop start, blows fast, black screen and stop, again, again... Sometimes turn on with caps lock only turned on (no flashing) and no activity.

This bios saved me many times...maybe u need to use BCU to put back the right DMI info

Hello, so I flashed it this morning but it's very difficult to turn it on. After several attempts, it finally rebooted, but runs a continuous bios recovery by stopping and restarting.

Hello, the pc doesn't boot, the power LED flashes orange and white, the shift key flashes white for a few seconds, goes out, then flashes white again for a few seconds, in a loop. The PC tries to start up but shuts down just as quickly.

I also tried your bios again this morning with another program. The pc did several startups, with recovery of its identity from the Embedded Controller due to data mismatch. After several restart corruption IME firmware so continue to complete the full recovery process on the Intel ME... after several restart the laptop seems to be behaving normally again. I go to the bios and reset the security settings and save. Laptop restart aks to confirm, etc...Everything seems to be back to normal.

I reconnect the cmos battery, the battery, and back cover the pc doesn't boot anymore.

no LEDs anywhere. I decide to remove the bottom cover and the pc boots up, but nothing appears on the screen.

I disconnect the battery, discharge the PC for 30 seconds, then connect the charger and press the power button: the PC starts up the fan blows hard but nothing is displayed during several seconds and finally the PC shuts down.

Orange LED on charging port, no longer possible to switch on laptop.

solder the bios chip well then its will turn on again

[Genova]

Thanks for answering, but I didn't unsolder the chip.I only work with clamps or pin probe.

Reflash it again
Its better to do it by desoldering and soldering
Choose a working bios then rewrite your laptop information using BCU
If you don't know how i will help you

[Genova]

I've already wasted too much time on this laptop. It gave me hope by behaving normally, but then it started to malfunction again.
I'll try again later, but thanks to those who replied to my post.
